 I'm running xscreensaver (5.11-1+b1) and it is configured to set the
 display to standby after 10 Minutes and to suspend after 20
 minutes. After approximately 10-20 minutes (i.e. after switching to
 standby mode or switching to suspend mode -- will debiug it further),
 the screen was blank and without backlight as expected, but neither
 moving the mouse nor hitting a key on the keyboard (not even switching
 to a virtual console with Ctrl-Alt-F1) changed something and it stayed
 dark.

This does no more happen if I uncheck the display power management
check box in xscreensaver's preferences. (Which can count as
workaround.)

It nevertheless happens, too, if X itself blanks the screen in the
case xscreensaver is not running. So it does not seem to be
xscreensaver related at all, but probably DPMS related.

 But pressing the EeePC's power button cleanly shuts down the computer,
 so the system does not hang, just the screen doesn't come back to live
 until I power cycle it (and then the first thing I see again are BIOS
 messages). Since I'm currently not at home, I don't have a second
 machine to ssh into the EeePC and look what's going on in detail.

In the meanwhile I tried to login via ssh remotely in that state.
Works fine, but also chvt 1 or restarting or killing X didn't change
anything.

Pressing Fn-F1 (Sleep in general, Suspend-to-RAM in my case) and then
the power button to wakeup to EeePC again reactivates the screen and
can be seen as workaround. It's nevertheless quite annoying, so I'm
back on the last 2.6.36 from experimental.
